Why is the calling of apostles important for Christians?

The significance of the apostles' calling lies in its foundational impact on the Christian faith. The apostles were chosen to bear witness to Christ and to convey the gospel message, as seen in Ephesians 2:20, which indicates the church is built on the foundation of the apostles and prophets. This foundation has shaped Christian doctrine and practice throughout the centuries. By understanding their unique calling and the authority they possessed, Christians are reminded of the roots of their faith and the divine providence that governs the church. Their teachings form an essential part of Scripture and provide guidance for truth in the life of the church.
